php - PHP-字符串修剪

Question

请帮我。

$str = "col_1          col_2  col_3
row1 row2 row3
row12 row22        row33";

$arr = explode("\n", $str);

foreach($arr as $line)
{
   $temp_arr = explode(WHAT HERE, $line); 
}

我如何将每一行爆炸成数组？
我要 $temp_arr[0] = col_1， $temp_arr[1] = col2， $temp_arr[2] = col_3
下一行将具有 $temp_arr[0] = row1， $temp_arr[1] = row2

你们真棒。它适用于我的示例，但不适用于我的实际问题。我导出Windows XP进程，并希望将其爆炸。

更换

$temp_arr = explode(WHAT HERE, $line);

与

$temp_arr = preg_split('/\s+/', $line, -1, PREG_SPLIT_NO_EMPTY);

编辑：添加了PREG_SPLIT_NO_EMPTY

好，所以您的问题有所改变。该代码应完全满足您的要求：

$processes = 'the list you posted';

$temp = preg_split('/\s*(?:\r?\n)+/', $processes, -1, PREG_SPLIT_NO_EMPTY);
$process_list = array();
foreach ($temp as $process) {
    $process_list[] = array_pad( // array_pad makes the length consistent
        preg_split(
            '/\s{2,}/', // match only 2 or more consecutive spaces for splitting
            $process,
            3,
            PREG_SPLIT_NO_EMPTY), // ignore empty matches (i.e., end of line)
        3, // pad array to a length of 3
        ''
    );
}

$process_list_final = array();
$process_list_titles = array_shift($process_list);

foreach ($process_list as &$plist_item) {
    $plist_item = array_combine($process_list_titles, $plist_item);
}

它可能需要一些清理，但是您可以自己完成=）

一些功能供您查找：

array_pad
array_shift
array_combine
